note 127252 added to language.constants.magic

If PHP is run inside a web server request there is an important difference between the __DIR__ constant and $_SERVER['DOCUMENT_ROOT']. Where __DIR__ of a PHP script contained within a sub-folder will include the complete server path $_SERVER['DOCUMENT_ROOT'] will contain a server path up to the _root_ of the application. This can be helpful when for instance an auto-loader is defined in an include file sitting inside a sub-folder and where the classes are located in another folder at the root of the application. ---- Server IP: 45.112.84.4 Probable Submitter: 80.90.12.131 (proxied: 83.97.81.249) ---- Manual Page -- https://php.net/manual/en/language.constants.magic.php Edit -- https://main.php.net/note/edit/127252 Del: integrated -- https://main.php.net/note/delete/127252/integrated Del: useless -- https://main.php.net/note/delete/127252/useless Del: bad code -- https://main.php.net/note/delete/127252/bad+code Del: spam -- https://main.php.net/note/delete/127252/spam Del: non-english -- https://main.php.net/note/delete/127252/non-english Del: in docs -- https://main.php.net/note/delete/127252/in+docs Del: other reasons-- https://main.php.net/note/delete/127252 Reject -- https://main.php.net/note/reject/127252 Search -- https://main.php.net/manage/user-notes.php
